Abstract

A display panel includes: a first substrate; a display unit disposed on a principal surface of the first substrate; a first sealing wall disposed in a frame shape on the principal surface of the first substrate, along an outer periphery of the first substrate; a second sealing wall disposed in a frame shape on the principal surface of the first substrate, along an outer periphery of the display unit; a desiccant material filled between the first sealing wall and the second sealing wall; a protective material filled on the display unit, in a region surrounded by the second sealing wall; and a second substrate. The second sealing wall covers at least a portion of a surface of the display unit opposite a surface of the display unit which is in contact with the first substrate.

Claims

exact text as granted — not AI-modified

The invention claimed is: 
     
       1. A display panel comprising:
 a first substrate; 
 a display unit disposed on a principal surface of the first substrate; 
 a first sealing wall disposed in a frame shape on the principal surface of the first substrate, along an outer periphery of the first substrate; 
 a second sealing wall disposed in a frame shape on the principal surface of the first substrate, along an outer periphery of the display unit; 
 a desiccant material filled between the first sealing wall and the second sealing wall; 
 a protective material filled on the display unit, in a region surrounded by the second sealing wall; and 
 a second substrate disposed on the first sealing wall, the second sealing wall, the desiccant material, and the protective material, 
 wherein the second sealing wall covers at least a portion of a surface of the display unit, the surface being opposite a surface of the display unit which is in contact with the first substrate; and wherein the outer periphery of the display unit has a length greater than a length of an inner periphery of the second sealing wall and less than a length of an outer periphery of the second sealing wall. 
 
     
     
       2. The display panel according to  claim 1 ,
 wherein the second sealing wall has a viscosity greater than a viscosity of the desiccant material and a viscosity of the protective material.
